Untreated Colombian Emerald 0.95 ct Oval – No Oil, Natural Loose Stone

Looking for an emerald exactly as nature made it? Almost every emerald on the market is oiled or resin-filled to hide its natural inclusions. This one isn't. It's a natural Colombian emerald with no oil, no resin and no treatment of any kind, and a rich, vivid green. At almost a carat, it's a classic oval size for an engagement ring that's a little different, with a story behind it.

• Natural. Untreated. Colombian green. Made to be remembered.
• Natural Colombian emerald, 0.95 ct oval, 7.2 × 6.0 mm
• Untreated: no oil, no resin, no treatment of any kind
• Rich vivid green, Muzo colour grade
• A classic oval size for an engagement ring that's a little different
• A loose natural emerald from Colombia, sold unmounted. There is only one of this stone.

Why "no oil" matters

Oiling is the standard, accepted treatment for emerald, and it's used on almost every stone sold. An untreated emerald shows its true clarity and colour, with nothing added and nothing to wear away over time.

Why Colombia

Colombia has produced fine emeralds for centuries. This stone has the warm, vivid green the trade calls a Muzo colour grade, named after Colombia's most famous mine (colour grade only; the specific mine is not specified).

For the engagement ring buyer

• Almost 1 carat, a classic oval centre stone
• 7.2 × 6.0 mm, a standard setting size that fits ready-made oval settings
• Lovely in a solitaire, a halo or set east-west
• Yellow gold warms the green, and white gold or platinum gives a crisp contrast
• Emerald is softer than sapphire, so a protective setting such as a bezel or a halo is a good choice for everyday wear

A gemstone for him: the men's signet ring

At Roho Jewels, we believe men deserve beautiful gemstones too. A natural Colombian emerald set into a signet ring is a bold, personal alternative to a plain metal signet: one-of-a-kind, full of character, and a ring he'll wear for decades and one day pass down.

• Signet face: at 7.2 × 6 mm, this stone suits a signet face of about 11–14 mm, a classic small signet or pinky ring
• Setting: flush (gypsy), bezel or half-bezel keeps it low and smooth, with no claws to catch on sleeves or gloves
• Depth: the stone is 3.6 mm deep, so ask your jeweler for a signet head at least 4.6 mm deep
• Metal: rich in yellow gold, sharp in white gold or platinum, rugged in oxidised sterling silver
• Wear: Mohs 7.5–8. A flush or bezel setting protects the edges, making it ideal for a dress signet or careful everyday wear
• Perfect for: husbands, fathers, grooms, graduates, milestone birthdays, or a signet he buys for himself

Birthstone meaning

Emerald is the birthstone for May and the traditional gemstone for 20th and 35th wedding anniversaries, long a symbol of love, renewal and loyalty.
